4 Claims.

This invention relates to retaining means for thread guides usually ofpor'celain and used extensively in thread twisting and winding machines.

More particularly the invention relates to means for fastening'the wires forming the retaining means on to the traverse'bar of the winding or twisting machine.

An object of the present invention is to provide a simple, inexpensive and easily attached retainer that will enable a porcelain or other form of thread guide to be resiliently retained in adjusted position so that the guide may be readily positioned on or removed from the traverse bar. l Another object of the invention is to so fasten the retainer wire to the traverse bar that the same pressure will be applied to adjacent guides, the opposite ends of which are retained by the oppositely extending ends of one retainer wire. 20 One feature that enables me to obtain the above objects is that a loop formed in the retainer wire is set into a deep longitudinal groove formed vertically in the traverse bar, there being a transverse screw through the bar intersecting the groove and disposed above the loop formed in the retainer wire, the loop entering the groove and extending below and around the screw so that the wire may tilt to any oblique position while being always disposed longitudinally and w vertically in the traverse bar.

With the above and other objects in view, the invention includes the features of construction and operation set forth in the following specification and illustrated in the accompanying drawmg.

In the accompanying drawing annexed hereto and forming a part of this specification, I have shown the invention designed for embodiment in a conventional form of textile winding ma- 40 chine but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon 45 for that purpose.

In the drawing:

Fig. 1 is a fragmentary front elevation of a traverse bar having the present guide retaining means applied thereto; and;

50 Figs. 2 and 3 are transverse sectional views taken respectively upon the planes of lines 2-2 and 3-3 in Fig. 1.

In the above mentioned drawing, there has been shown but one embodiment of the inven- 55 tion which is now deemed preferable, but it is Briefly and'in'its preferred aspect the inven- 5 tion may include the following principal parts: first, a traverse bar having a deep but narrow longitudinal slot cut vertically into its upper edge or surface;.second, an elongated wire having a central loopi entering the groove and having its ends extending above the bar inopposite directions; and third, a transverse member such as a screw intersecting the groove and retaining the loop of the retainer against removal but permitting freedom of oblique movement in a vertical plane.

Referring more in detail to the figures of the drawing there is shown one end of a traverse bar ill of a usual or conventional form used in textile machines. Positioned along this traverse go bar H) are a number of guides H usually of porcelain equally spaced along the bar. Each of the guides H is provided with a thread notch l2 of the usual form and in the upper surface is cut or formed a shallow longitudinal groove [3.

The retainer wire M for the guides II is bent as shown in Fig. 1 to form a central depending loop l5 and providing oppositely extending resilient arms or ends 2| extending therefrom. These ends 2| enter the grooves i3 of adjacent guides H and force the guides against the surface of the bar It and thus retain the guides in position. Each retainer wire M has its loop l5 disposed within a vertical longitudinally extending groove l6 formed in the traverse bar It. The groove I6 is wide enough only for the diameter of the wire l4 so that the retainer is maintained in a vertical plane.

To retain the wire I4 in place but to permit tilting movement to equalize the pressure exerted by the ends 2| on the guides II a single member I! is used. This retaining member I"! may preferably be in the form of a screw disposed transversely of the bar I 0 and intercepting the narrow groove "5 at a point above the loop l5.

For the end guide II a special retainer wire is made use of for engagement with one side as shown in Fig. 1. This wire I8 may be formed as shown having one end shaped to correspond to ends 2| and to fit the groove I3 within the guide II. The opposite end of the wire I 8 enters the groove I 6 and is looped as shown at IS. A screw 20 is disposed transversely of the traverse bar IIJ similarly to screws passes within the loop l9.

Both forms of retainer wires [4 and 18 have their loop and end portions so formed that all parts of the wires lie in a single plane. The wires therefore require minimum bending operations and may be completely formed in a single operation. a

I claim as my invention:

1. A retainer for thread guides comprising in combination a traverse bar having a longitudinal :oeve formed therein, thread guides mounted thereon, a Wire having a central open loop adapted to enter the groove in said bar, oppositely extending end portions of said wire resiliently engaging against the upper surfaces of and holding adjacent guides on said bar, the entire length of retainer being substantially in a single plane. and a holding member for said wire extending transversely through the bar, intercepting said groove and passing freely through said loop.

2. A thread guide for textile machines comprising in'combination a traverse bar having a narrow vertical groove extending longitudinally therein, thread guides resting on said bar, wire retainers for said guides having a looped portion therein and having their ends resiliently engaging against the upper surfaces of adjacent guides, the entire length of said retainers being substanl! and preferably tially in a single plane, and holding means for said wires comprising transversely extending members passing through the groove in said bar and disposed to pass within the loop portion of said wires.

3. A thread guide for textile machines comprising in combination a traverse bar having a narrow vertical groove extending longitudinally therein, thread guides resting on said bar, wire retainers for said guides having a looped central portion therein entering said slot and the end portions thereof resiliently engaging over the upper surfaces of said guides, the entire length of said retainers being in a single plane, and holding means for said wires comprising transversely extending members passing through said bar and intercepting said slot within said loops, whereby said wire will be retained in position within said slot and will be free to angularly adjust itself while being retained in a vertical plane.

4. A retainer for thread guides comprising in combination a traverse bar having a longitudinal groove formed therein, thread guides mounted thereon, a wire having a central loop adapted to fit closely within the groove in said bar, oppositely extending resilient portions of said wire having their ends engaging over the upper surfaces of and holding adjacent guides against said bar, the loop and end portions of said wire being in a single plane, and a transverse screw intercepting said groove and passing through said loop, whereby said wire is retained in position.
